Virual Oral Question and Answer


IEEE/ICACT20210216 Question.5 Questioner: hjcho1@korea.ac.kr 2021-02-10 오전 10:32:35	IEEE/ICACT20210216 Answer.5 Answer by Auhor wsub@korea.ac.kr 2021-02-10 오전 10:32:35
That's interesting. I have one question. When going from the checkBidding location to the end location, the bidder's model updates the beneficiaryAccount value. Is it reasonable to do it in the bidder's model? Shouldn't the smart contract model update the seller's balance?	Hello, Thank you for your question. The reasons for updating the price in the bidder model in the proposed model are as follows: This is because I thought that if the bidder was a reasonable price(wants to purchase) and made a transaction, time was an important property in the auction, so I thought that the price should change immediately in bidder model. Of course, when a transaction occurs, checking whether the transaction is correct is done through proof of work inside the blockchain. The current model is a high-level model, not that level model. If you model a low-level model by subdividing it, I think that price fluctuations should occur in the contract model as the questioner said. Thanks for the good question. We will refer to it in future research. Thanks.
